Man, that was it; or at least, it doesn’t complain about IPX not being installed anymore. I didn’t know you could just make up a name for any library not listed and it would still know to override it. Thanks! I’ll run a LAN test between my desktop and Steam Deck, and if it’s all working, I’ll document it on PC Gaming Wiki and update this thread.
This is exactly what I thought was happening, and theoretically, it’s exactly what I recreated in Heroic, give or take the frame rate limit. However, while things like the controller remapping config files are clearly working, the IPX networking fix is not. For one, things like wsock32, verbatim anyway, aren’t present in the list of library overrides at all, and that list of libraries I put in the original post, that appear in the Lutris install, don’t appear in the Lutris script. I looked for some extra scripts in the github directories to see if there were other instructions that were being run outside of this script (that’s what you told me to look for, right?), but the only thing I found in there seemed to be a copy of part of this same Lutris script.
Ads in Windows 10 back in like 2017 were major contributing factors for me to switch back then. But then when I mentioned I got ads in Windows 10, people looked at me like I had two heads. Perhaps there was some kind of A/B testing going on, and I was the unlucky one. This followed a forced update from Windows 8 Professional to Windows 10 Home, so I lost some control over my PC in that transition, as they took Pro features away from me.
Worth a shot. I’m on Proton Experimental. But the other major differences between our systems are OS and GPU. I’m on Kubuntu 24.04 and an RX 6800 XT with mesa drivers.
